Background: Reproductive performance is one of the major determinants for the economic improvement of a dairy farm. Endometritis and other uterine complications cause decrease the pregnancy rate. In this study, the genital changes and haemato-biochemical profile of crossbred dairy cows affected with endometritis was studied to evolve a suitable treatment protocol in order to improve reproductive efficiency. Methods: Crossbred cow affected with endometritis were selected based on mucopurulent vaginal discharge at estrus and tested positive for white side test. Animals were divided randomly into 8 groups with 24 animals in each group. Different therapeutic regimens fortified with supportive treatment were opted. The therapeutic regimens were supportive therapy having bypass fat, vitamins and minerals, Lugol’s iodine, Lugol’s iodine with supportive therapy, intrauterine (IU) antibiotic, IU antibiotic with supportive therapy, E. coli. LPS, E. coli. LPS with supportive therapy and control group respectively. Efficacy of each treatment regimen was based on first service conception rate (FSCR). Result: Of all the therapeutic regimens, fortification of Lugol’s iodine with supportive therapy resulted in higher FSCR (83.33%) indicating better applicability as a treatment tool for endometritis in crossbred cows.

ABSTRACT We examined how a dietary supplement affects the prevalence of antibiotic-resistant Escherichia coli on a dairy farm in Washington State. Between 2001 and 2004 the prevalence of fecal E. coli strains resistant to streptomycin, sulfadiazine, and tetracycline (SSuT strains) declined from 59.2% to 26.1% in the calf population. In 2003 the dairy discontinued use of a dietary supplement, and we hypothesized that the decline in prevalence of SSuT strains was related to this change in management. To test this we established three treatments in which calves received no supplement, the dietary supplement with oxytetracycline, or the dietary supplement without oxytetracycline. Calves receiving either dietary supplement had a significantly higher prevalence of SSuT E. coli than the no-supplement control group (≈37% versus 20%, respectively; P = 0.03). Importantly, there was no evidence that oxytetracycline contributed to an increased prevalence of fecal SSuT E. coli. We compared the growth characteristics of SSuT and non-SSuT E. coli in LB broth enriched with either the complete dietary supplement or its individual constituents. Both the complete dietary supplement and its vitamin D component supported a significantly higher cell density of SSuT strains (P = 0.003 and P = 0.001, respectively). The dry milk and vitamin A components of the dietary supplement did not support different cell densities. These results were consistent with selection and maintenance of SSuT E. coli due to environmental components independent of antibiotic selection.

Abstract BackgroundIn postpartum dairy cows, dry matter intake (DMI) was dramatically decreased, resulting in the decreased plasma glucose, a negative energy balance (NEB), and negative nutrient balance. Asprosin, which is a fasting-induced glucogenic protein hormone secreted by adipose tissue, promotes plasma glucose level. However, effect of asprosin on the hepatic glucose output in primary bovine hepatocytes and plasma asprosin level in postpartum dairy cows remain not reported. ResultsOur results demonstrated that fibrillin 1 (FBN1) showed much higher mRNA expression in mammary gland and adipose tissue compared with heart, liver, spleen, lung, and kidney. The recombinant bovine His-asprosin was not found in supernatant of E. coli lysate, but present in the inclusion bodies in E. coli. The bovine His-asprosin proteins were > 90 % pure by Coomassie Blue-stained SDS-PAGE gel analysis. Asprosin enhanced (P = 0.031) the mRNA expression of PCK2 in primary bovine hepatocyte compared with control group, and FBP1 tended (P = 0.086) to be upregulated in primary bovine hepatocyte treated by Asprosin. Remarkably, glucose output was increased (P = 0.03) in primary bovine hepatocytes exposed to asprosin than control group. In addition, Asprosin can promote PKA activity in primary bovine hepatocytes, but not AKT. Asprosin was observed to be present in bovine plasma at consistent nanomolar levels. The postpartum cows exhibited (P = 0.003) much higher level of circulating asprosin compared with mid-lactation dairy cows. ConclusionsThese findings indicate that asprosin should be further considered for use as a novel therapy strategy for NEB and negative nutrient balance in postpartum period.

To promote the provision of animal-friendly housing and management exceeding the minimal legal standards, the Swiss government offers direct payments through two programs for several farm animal species. In dairy cows the BTS program pays for group housing systems with a comfortable lying area separated from the feeding area. The other program, the RAUS, requires that cows receive regular exercise in an outdoor run in the winter and a pasture during summer. The aim of the study was to analyze the relationship between the two Swiss direct payment programs and the veterinary and insemination costs for dairy cows. We used a large sample of more than 21,000 dairy farm observations from 2004 to 2014 obtained from the Swiss Farm Accountancy Data Network. A propensity score weighting was combined with a linear regression model to estimate the doubly robust treatment effects of the BTS and/or RAUS programs on dairying and breeding. Compared to the control group, that is, farms participating in neither program, farms in the RAUS tended to reduce their veterinary costs by 2% (CHF 4.71). Participation in both the BTS and RAUS programs resulted in a 10% cost reduction (CHF 19.32). An analysis of the effects of participation in both programs, with farms participating in only the RAUS as the control group, indicated a cost reduction of 7% for the farms participating in both programs (CHF 13.54). In contrast, participation in the RAUS only or in the RAUS and the BTS did not have a significant effect on insemination costs. The results thus indicate that the implementation of higher welfare standards can have a positive effect on the economic situation of a farm.

Clinical endometritis (CE) is a serious disease leading to poor reproductive performances in lactating dairy cows, thus diminishing farm profitability. To preserve optimum reproductive efficiency, various strategies and therapeutic approaches have been proposed to manage cows with CE, often with contradictory results. Thus, investigating new paths to CE treatment is economically important. The aim of the present study was to test the efficacy of three therapeutic protocols on the clinical cure rate of CE, and improvement of reproductive performance. Cows with CE (n=42), 21–38 days in milk (DIM), were assigned to three treatment groups: PGF: cows (n=19) were treated systemically with two doses of d-cloprostenol, a PGF2α analogue, at 14-days intervals; CEFAX: cows (n=10) received an intrauterine infusion of the combined antibiotics Cefacetrile and Rifaximin; and NAX: cows (n=13) received systemic treatment with Ceftiofur crystalline free acid (CCFA). A control group included cows (n=36) free from CE (healthy group: HE). All cows were clinically re-examined after the end of the treatment protocol. The clinical cure rate was 73.7%, 80% and 69.2% in PGF, CEFAX, and NAX groups, respectively (P>0.05). The HE group had a significantly shorter calving to first service interval compared to CEFAX and PGF groups (P<0.05), however the difference was not significant with NAX group. The mean calving to fertilizing service interval (CFI) was slightly higher in all three treatment groups compared to the HE group, however the difference was not significant (P>0.05). CEFAX protocol resulted in shorter but not statistically significant CFI, compared to the PGF and NAX protocols. Services per conception rate were slightly lower (1.7) in the CEFAX group compared to HE (1.75), PGF (1.84) and NAX (2.23) groups, however these differences were not significant. First service conception rate and conception rate at 105 DIM did not differ statistically between the treatment groups. While the difference was not significant, CEFAX protocol had slightly better cure rate for CE, reducing the number of services per conception and boosting the resumption of ovarian activity after calving. Validating these finding on a larger herd size will improve the accuracy of these findings.

The present research was carried out on indigenous beef cattle to study the effect of iodine formulations on body weight and hematology by using iodide salt and Lugol's iodine irrespective of feed and management in dairy farm, Bangladesh Agricultural University in collaboration with the Department of Pharmacology, Bangladesh Agricultural University for the period of 2 months from August to September 2005. A total of 20 male bull of 2 years old were selected, weighed ranged from 80-100kg and randomly divided into four groups as A, B, C and D. Group A was treated with non- iodide salt @ 25mg/ kg b.wt, group B treated with iodide salt @ 25mg/ kg b.wt, group C treated with IV injection of 2 % Lugol's iodine @ 10 mg/kg b. wt and group D were kept as control. After treatment, blood parameters and body weight were recorded on 30th and 60th day. Highest weight gain was recorded in Lugol's iodine treated group, about 7.09 % for weight gain compared with the control group. The result reveals that use of iodine formulation is an effective way of increasing meat production and weight gain in indigenous beef cattle of Bangladesh.

Intensification of dairying on irrigated pastures has led to concern over the microbial quality of shallow groundwater used for drinking purposes. The effects of intensive dairying and border-strip irrigation on the leaching of E. coli and Campylobacter to shallow groundwater were assessed over a three-year period in the Waikakahi catchment, Canterbury, New Zealand. Well selection excluded other sources of contamination so that the effect of dairying with border-strip irrigation could be assessed. Groundwater samples (135) were collected, mostly during the irrigation season, with E. coli being detected in 75% of samples. Campylobacter was identified in 16 samples (12%). A risk assessment of drinking water with these levels of Campylobacter was undertaken. A probability distribution was fitted to the observed Campylobacter data and the @RISK modeling software was used, assuming a dose response relationship for Campylobacter and consumption of 1 L/day of water. The probability of infection on any given day in the study area was estimated at 0.50% to 0.76%, giving an estimated probability of infection during the irrigation season of 60% to 75%. An epidemiological assessment of the Canterbury region comparing areas encompassing dairy within major irrigation schemes (∼55% border-strip irrigation) to two control groups was undertaken. Control group 1 (CG1) encompasses areas of dairying without major irrigation schemes, and a second larger control group (CG2) comprises the rest of the Canterbury region. Comparisons of the subject group to control groups indicated that there was a statistically significant increase in age-standardised rates of campylobacteriosis (CG1 Relative Risk (RR)=1.51 (95% CI = 1.31-1.75); CG2 RR = 1.51 (1.33–1.72)); cryptosporidiosis (CG1 RR = 2.08 (1.55–2.79); CG2 RR = 5.33 (4.12–6.90)); and salmonellosis (CG2 RR = 2.05 (1.55–2.71)).

The aim of this study was to determine if cimetidine in addition to N-acetylcysteine and standard supportive care provide additional hepatoprotection following acute acetaminophen poisoning. It was designed as a prospective study with alternate month treatment protocol, and the work was carried out at a regional certified poison information centre. For a 2-year period, consultations received by the Rocky Mountain Poison Center involving acute aceta minophen overdose patients with a serum level above the nomogram line, but who would not receive N-acetylcys tine therapy until at least 8 h postingestion, were prospec tively evaluated for adjunctive treatment with cimetidine. All patients received standard supportive therapy and N- acetylcysteine treatment. During odd numbered months, cimetidine 300 mg was administered intravenously every 6 h for the duration of N-acetylcysteine therapy. Forty-one cimetidine treated patients were compared to 66 patients in the control group. The peak measured AST levels (+/- s.e.) were 1259+/-330 and 1301+/-451 for the control and cimetidine treatment groups, respectively (P = 0.94). Fourteen of 64 patients (21%) in the control group and 8/41 patients (20%) in the cimetidine group developed an AST > 1000 IUL-1. There were no statistical differences between the cimetidine-treated and control groups when classified by AST<100IUL -1, 100- 1000IUL-1, or >1000IUL-1. The addition of cimetidine therapy to standard N- acetylcysteine treatment did not provide additional hepatoprotection in acutely acetaminophen poisoned patients when treatment was started later than 8 h post overdose. Larger doses of cimetidine along with more fre quent or continuous intravenous administration may war rant further study.

Цель исследования. Разработка методов сопроводительной терапии для защиты нормальных органов и тканей, входящих в зону облучения. Методы. В исследование включено 112 больных раком шейки и тела матки после комбинированного или самостоятельного лучевого лечения с 2012 по 2016 гг. У 71 пациентки основной группы в качестве терапии сопровождения применяли гидрогель с деринатом и у 41 больной группы контроля - традиционные методы профилактики (масло оливковое, подсолнечное, метилурациловая мазь). Для профилактики эпителиита слизистой влагалища и шейки матки в основной группе использовали гидрогель в виде аппликаций с первого дня облучения. Для профилактики лучевого ректита гидрогель вводили в прямую кишку 1 раз в день с первого дня облучения. Инстилляции гидрогеля в мочевой пузырь начинали только при развитии первых признаков клинической картины цистита. Пациенткам контрольной группы для профилактики лучевых реакций проводились масляные, мазевые аппликации во влагалище, масляные микроклизмы в прямую кишку с первого дня облучения. Лечение лучевого цистита проводили с помощью растительных диуретиков, уросептиков. Результаты. Применение гидрогеля с деринатом позволило провести курс лучевой терапии без перерыва у 84,5% (60/71) больных, в контрольной группе - лишь у 48,8% (20/41). Лучевые циститы возникали в 2,5 раза реже (25,3% ± 3,3 против 63,4% ± 2,7, р<0,01). Анализ степени выраженности лучевого цистита по RTOG в двух группах показал, что у 75% больных основной группы наблюдалась I степень, у 25% - II степень, III и IV степени не отмечено, тогда как в контрольной группе лучевой цистит I степени развился у 44% пациенток, II - 40% и III - 16% больных. Применение гидрогеля снизило частоту лучевых ректитов в 2 раза (26,7% ± 3,3 против 53,7% ± 3,2 р<0,1).При использовании ежедневных аппликаций гидрогеля с деринатом со стороны слизистой оболочки влагалища и шейки матки преобладали эпителииты I степени (53,5%), II степень наблюдалась у 29,5% и III степень лучевой реакции - лишь в 16,9% случаев, IV степень реакции не отмечена. В контрольной группе эти показатели составили 26,8%, 24,3%, 31,7% и 17,2% соответственно. Разработаны цитологические критерии оценки течения лучевых реакций слизистой влагалища. Выделены три степени изменения цитограммы, которые коррелировали с клинической картиной. В основной группе лучевые изменения I степени зафиксированы в 4,5 раза чаще (52 ± 9,9% против 11,5 ± 6,3%, р<0,002), а III степень представлена в 3,8 раза реже, чем в контрольной группе (12 ± 6,5% против 46,1 ± 9,8%, р<0,003). Заключение. Применение гидрогелевого материала с деринатом в качестве препарата сопроводительной терапии во время курса облучения позволяет уменьшить частоту и степень выраженности лучевых повреждений со стороны слизистой влагалища, мочевого пузыря и прямой кишки, провести курс лучевой терапии без перерыва и улучшить качество жизни пациенток. Objective. Development of methods for accompanying therapy to protect normal organs and tissues in the irradiation zone. Method. The study included 112 patients with cervical and endometrial cancer after combined or independent radiotherapy from 2012 to 2016. In 71 female patients of the main group, Derinat with hydrogel was applied as a supportive therapy and in 41 patients of the control group, conventional prevention methods (olive oil, sunflower oil, methyluracyl ointment) were applied. For prevention of vaginal mucosal and cervical epitheliitis in the main group, hydrogel was used as applications from the first radiation day. For prevention of radiation proctitis, hydrogel was injected into the rectum once daily from the first radiation day. Hydrogel instillations into the bladder were started only with the first clinical signs of cystitis. For prevention of radiation reactions, vaginal oil and ointment and rectal oil micro-enema were administered to patients of the control group from the first day of irradiation. Radiation cystitis was treated with vegetable diuretics and uroseptic drugs. Results. Using the hydrogel with Derinat allowed to administer a course of radiotherapy without interruption in 84.5% (60/71) of patients and only in 48.8% (20/41) in the control group. Radiation cystitis occurred 60% less frequently (25.3% ± 3.3 versus 63.4% ± 2.7, p <0.01). Analysis of radiation cystitis severity in two groups (according to RTOG) showed that 75% of patients in the main group had grade I and 25% had grade II. Grade III and grade IV did not occur. At the same time, in the control group, grade I radiation cystitis developed in 44% of patients, grade II - in 40%, and grade III - in 16% of patients. The hydrogel treatment halved the frequency of radiation proctitis (26.7% ± 3.3 vs. 53.7% ± 3.2 p <0.1). With daily application of the hydrogel with Derinat, grade I epitheliitis (53.5%) predominated in vaginal and cervical mucosa, grade II was observed in 29.5%, and grade III radiation reaction - only in 16.9% of cases; grade IV reaction was not observed. In the control group, these proportions were 26.8%, 24.3%, 31.7%, and 17.2%, respectively. Cytological criteria were developed to evaluate the course of radiation reactions in the vaginal mucosa. Three degrees of change in the cytogram were identified, which correlated with clinical picture. In the main group, incidence of grade I radiation-induced changes was increased by more than 350% (52 ± 9.9% vs. 11.5 ± 6.3%, p <0.002), and incidence of grade III was decreased by more than 70% compared to the control group (12 ± 6.5% vs. 46.1 ± 9.8%, p <0.003). Conclusion. Using the hydrogel material with Derinat as an accompanying therapy during the course of irradiation allows to reduce frequency and severity of radiation injuries of the vaginal mucosa, bladder, and rectum, administer an uninterrupted course of radiotherapy, and improve the quality of life of patients.

This study investigated the efficacy of intrauterine infusion of a chitosan solution (CHT) on uterine recovery in early postpartum dairy cows with or without endometritis, and their subsequent reproductive performance. In Experiment 1, cows with endometritis at 3 weeks postpartum were administered CHT (n = 5) and prostaglandin F2α (PGF2α) (n = 4). Untreated cows (n = 7) served as the control group. In Experiment 2, 18 cows with a normally recovered uterus at the fresh cow check (mean, 35 days postpartum) were assigned to the CHT (n = 10) and control (n = 8) groups, and intrauterine infusion was conducted in the CHT group. Overall, in Experiment 1, the percentage of polymorphonuclear leukocytes significantly declined in the CHT group (32.3 ± 10.2 to 5.5 ± 2.4, p < 0.05) from week 3 to week 5, but no decline occurred in the PGF2α and control groups. In Experiment 2, the CHT and control groups showed no significant differences in reproductive parameters, suggesting the absence of adverse effects of CHT on fertility. These results suggest that intrauterine infusion of CHT in the early postpartum period effectively accelerates uterine recovery from endometritis and might be a suitable replacement for PGF2α administration.

A study was carried out from August 2017 to February 2018 on lactating dairy cows, one-humped dromedary camels, and goats to determine mastitis in the Bule Hora and Dugda Dawa districts of in Southern Ethiopia. Milk samples from 564 udder quarters and udder halves from 171 animals consisting of 60 dairy cows, 51 camels, and 60 goats were tested for mastitis. Sixty-four positive udder milk samples were cultured, and bacterial mastitis pathogens were isolated and identified. The antibiotic resistance of bacterial isolates from milk with mastitis was tested against nine antimicrobials commonly used in the study area. Cow- and quarter-level prevalence of mastitis in dairy cows, camels, and goats was 33.3%, 26.3%, and 25% and 17.6%, 14.5%, and 20%, respectively. In cattle, the prevalence was significantly higher in Dugda Dawa than in Bule Hora. Major bacterial isolates were coagulase-negative Staphylococcus species (39.1%), S. aureus (17.2%), S. hyicus (14.1%), and S. intermedius and Escherichia coli (9.4% each). In camels, udder abnormality and mastitis were significantly higher in late lactation than in early lactation. Mastitis tends to increase with parity in camels. E. coli isolates were highly resistant to spectinomycin, vancomycin, and doxycycline, whereas most S. aureus isolates were multidrug-resistant. Most of the rural and periurban communities in this area consume raw milk, which indicates a high risk of infection with multidrug-resistant bacteria. We recommend a community-focused training program to improve community awareness of the need to boil milk and the risk of raw milk consumption.
